ATDDC4 Series Installation & User’s Guide

Introduction

The AirTime ATDDC4 Wireless Digital Display Wall Clock is designed

with a 4-inch red LED display that can be viewed from distances over

100 feet. The optional 6 digit version provides 2 additional 2-inch

digits. The bright red display shows the hour and minutes or as an

option the hour, minutes and seconds; can be configured for a 12 or 24

Hour format; and keep time synchronized to a Lathem ATX series

transceiver’s wireless correction signal. The ATDDC4 series Wall Clocks

can be mounted directly to a wall, to a single gang outlet box or, with

optional mounting kits, as double-faced units from the wall or ceiling.

Clock Operation

When the ATDDC4 series Wall Clock is connected to 120vAC (24vAC

optional) power, it displays the firmware version for 3 seconds and

then changes to 12:00 AM. A flashing LED in the lower right indicates

that it is listening to acquire its initial synchronization signal. When a

signal is received the LED will extinguish and the internal clock will be

set. Note: It may take up to several minutes for the clock to initially

synchronize. After initial reception, the LED will only flash when future

sync signals are received. The clock will continuously listen and correct

itself as needed.

Clock Installation

Tools required for mounting the clock:

• Drill with a 5/16" bit

• Hammer

• Phillips head screwdriver

• Wall anchors

Separate the electronics from the enclosure and to set the Time

Display Format (12hr / 24hr). To do this, remove the plastic end caps,

each secured with two Phillips-head screws. Slide the front lens out of

the front track, then slide the circuit board and display out of the

second track in the enclosure. Carefully place each down on a smooth,

clean surface.

Time Formats

The ATDDC4 Series Wall Clocks can display either 12 Hour or 24 Hour

format. When in 12 Hour format, a red LED in the upper left corner of

the display indicates PM hours. When in 24 Hour format, the hours are

displays in Military style.

Mounting to a Wall

After deciding where to mount the clock, make two marks 12" apart

and horizontal. Note: If mounting near a ceiling, make sure the holes

are at least 2 1/4" away from the ceiling. Also, provide at least 16" of

side clearance on one side in order to remove the front panel.

Installation Steps

1. Drill a 5/16" hole at each mark

2. Insert a wall anchor and tap it flush to the wall with the hammer.

3. Insert a screw into each wall anchor leaving 1/4" exposed.

4. Line up the two keyholes on the back of the case and slip over the

two screws and tighten securely. ( The lower mounting holes can

be marked at this point, the case removed, holes drilled and wall

anchors installed if so desired)

Mounting to a Single Gang Box

Two mounting holes are located in the center of the case 2 1/4" apart

for mounting to a single gang wall box. A 7/8" hole is located between

the mounting holes that will accommodate conduit, if desired.

Note: If mounting near a ceiling, make sure the holes are at least 2-

1/4" away from the ceiling. Also, provide at least 16" of side clearance

on one side in order to remove the front panel.

Line the two holes in the case up to the single gang box and insert

proper screws for the single gang box and tighten securely.

Note: Make sure you have at least 16" of side clearance on one side in

order to remove the front panel assembly.

1. Place the two clock enclosures back to back and secure by inserting

a #10 screw through the four mounting holes using lock washers

and nuts supplied with the mounting kit.

2. Note: If the ATDDC4 clocks will be mounted too near a wall on one

side to secure the end caps, install the "wall side" end caps now.

3. Remove the center vent cap from the top of each ATDDC4 clock.

4. Line the two posts from the mounting plate up with the vent holes

of the ATDDC4 clocks. Insert the chase nipples through the vent

holes and secure to the mounting plate with a 15/16" wrench.

5. Slide the circuit board assemblies in partially and secure the

required wiring.

6. Slide the circuit board assemblies in fully, then slide the front

lenses into place. Note: the inside of the lens has a paper backing

which should not be removed. The end with wider paper should

go to the right. Replace the end caps and secure each with two

Phillips head screws.

7. Discard or store the two original end caps that the modified end

caps replaced.

Power Connection – Wall Mount

120vAC Electrical Supply can be brought into the ATDDC4 enclosure

from any of the six vent-hole positions, from the back, or from either

side. Conduit access is not available from the bottom.

Note: Optional plastic end-panels may be ordered (left VIS1551-L),

(right VIS1551-R) that have access holes pre-drilled for side access

Power Cord Installation

The optional AC Power Cord Kit (part# VSE0050) includes a 120vAC

Power Cord, metal fastener, 2 wire nuts and plastic strain relief that

can be installed through any of the available vent holes.

Strip away 1/2" of insulation from each wire of the power cord. Leave

eyelet on Ground Wire, if attached.

Remove the vent cap from the selected opening and insert the metal

fastener with the tabs toward the inside of the clock. Bend the tabs

down and away from the opening to secure it. Feed the cord through,

allowing sufficient length to attach the wires; including the ground.

Wrap the plastic strain relief around the cord close to the entry point,

squeeze it together and insert it into the metal fastener, to secure the

power cord to the enclosure.

Attaching Conduit

The Electrical Supply can be brought into the ATDDC4 enclosure from

any of the top three vent-hole positions, from the back, or from either

side. Conduit access is not available from the bottom.

Note: Optional plastic end-panels may be ordered (left VIS1551-L),

(right VIS1551-R) that have access holes pre-drilled to allow side

access.

If Conduit access is through either of the optional plastic end-

panels, Conduit should NOT be used to support the weight of the

Clock. The Clock must be properly secured to a wall.

Remove the vent cap from the selected mounting hole (if not accessing

through side panels). Attach the conduit with locking nut and extend

the wires into the enclosure.

Making the Connection

1. Slide the circuit board with display part-way back into the case.

Connect the two black wires from the circuit board to the power-

wires from the power cord or conduit using wire nuts. Connect the

Ground Wires from the circuit board and from the power source

(usually green) to the green ground screw on the inside of he

enclosure.

2. Slide the circuit board fully into place, then slide the front lens

into place. Note: the inside of the lens has a paper backing

which should not be removed. The end with wider paper should

go to the right. Replace the end caps and secure with the two

Phillips head screws.

3. When the clock is energized, it will set itself, upon receiving the

AirTime radio signal.

Double Mount – Wall

The ATDDC4 SERIES requires optional mounting kit (SAM0625)

Tools required for mounting the clock:

• Flat blade screwdriver

• Phillips head screwdriver

• 15/16" open end wrench

The double wall mount plate attaches to a double or single gang box

installed securely in the wall. Required wiring should be available

through the gang box at time of installation.

Installation Steps

1. Remove the two chase nipples from the mounting plate posts.

2. Secure the mounting plate securely to the gang box with the proper

screws. (not supplied)

Note: The long dimension of the mounting plate must be perpendicular

to the ground to assure proper alignment of wall clocks.

See remaining Wall

or Ceiling mount instructions below

Double-Mounting - Wall

1. Place the two clock enclosures back to back and secure by inserting

a #10 screw through the four mounting holes using lock washers

and nuts supplied with the mounting kit.

2. Attach the modified end cap to the clock’s end to be attached to

the wall mount plate using the original end cap screws.

3. Align the holes of end cap support plate with the holes in the

modified end cap and secure with 4 #6 Phillips head screws

(supplied).

4. Line the two posts from the mounting plate up with the two holes

of the modified end cap. Insert the chase nipples through the holes

of the modified end cap and secure to the mounting plate with a

15/16" wrench.
